Whilst HP was stealing the show with its Multi Jet Fusion (MJF) advancement at RAPID 2016, another yet unknown company showcased its own disruptive 3D printing platform. Not wishing to yet go public with news of its product offering, Mass.-based Rize was quietly telling attendees of its Augmented Polymer Deposition (APD), a patented 3D printing advancement able-bodied to turn it into engineering-grade parts with approximately no post-processing or toxic fumes and with functional capabilities rivaling those promised by HP with MJF.

Rize is now eager to go public with APD and the new Rize One 3D printing device—and there is a lot to go public of. For instance, the firm has aleager revealed its firstly beta customer, Reebok, which can use the advancement mostly for prototyping sneakers and plastic parts for athletic equipment.
In an interview with ENGINEERING.com, company President and CEO Frank Marangell was able-bodied to speak at excellent length of APD and its next impact on 3D printing present and next.
What is APD?
What is immediately most striking of APD is the advantages it has over other technologies, particularly futilized deposition modeling (FDM). Unlike FDM, as well as just of every other 3D printing process, APD needs quite little post-processing. Once a part comes off the print bed, assist structures are easily removed by hand.
No pliers, bead blasting, saws or sanding, as is a fewtimes needd with FDM and stereolithography (SLA) parts. No super glue baths, as is utilized with binder jetting. No high-pressure water jetting and chemical baths, synonymous with PolyJet or Multi Jet. And no excavation, as is seen in selective laser sintering.

Instead, APD blends thermoplastic extrusion, much like to FDM, with inkjetting, much like to PolyJet and Multi Jet. As a specialty thermoplastic called Rizium One, turn it intod by Rize in-house, is extruded onto the turn it into plate, an inkjet head is able-bodied to deposit a range of one-of-a-kind inks to print for a variety of applications.
In the case of effortless assist removal, this material is a repelling ink called Release One, which is deposited between the print and the assist structures. Whilst both the print and the assists are turn it intod of Rizium One, an engineering- and medical-grade plastic, the Release One prin factts the two of forming a sturdy bond. That way, once the print is fish, the assists can be easily removed of the part.

Ultimately, Rize estimates which effortless assist removal enable-bodieds users to cut total 3D printing turnaround time by 50 percent. Marangell relayed which, when a Reebok engineer visited Rize headquarters near Boston, “he had to go into the office at 6 am to start post-processing parts he had printed over night, otherwise the engineers weren’t going to get their parts which day. With the right solution, he mayn’t have needed to do which.”
In fact, Gary Rabinovitz, Additive Manufacturing Lab Manager at Reebok, is quoted in a new Rize
press release as saying, “We run our 3D printing devices 24/7 to turn it into the parts central to Reebok’s advancement and unfortunately, post processing has been a necessary but laborious and time-consuming process. An effortless-to-use, zero post-processing 3D printing device like Rize may dramatically improve workflow, allowing us to donate parts as much as 50 percent faster than much like technologies, while reducing the cost of labor, materials and equipment.”
The Properties of Rizium One
This effortless assist removal lends a few quite significant properties to the APD platform. First of all, APD allows for the Rize One to 3D print with quite sturdy thermoplastics, such as Rizium One. Whilst Marangell may not disclose the precise nature of Rizium One, he defined it as much like to polycarbonate (PC) in terms of durablity.

He said which, due to the way which the material bonds during the printing process, Rizium One is able-bodied to retain much of its isotropic properties, meaning which the parts printed in this material have approximately the same durablity in all directions (X,Y, and Z). This differs of most 3D printing technologies, which are unable-bodied to turn it into parts which are as sturdy in the Z-axis, due to the weak bonds which form between every layer of material. For this reason, these bonds are referred to as anisotropic.
“[Rizium One is] a compound thermoplastic which is high up in the engineering thermoplastic pyramid. It is not one material. It is not PC, acrylonitrile butadiene styrene (ABS), or polylactic acid… It has properties much like to PC. It has of the same durablity as PC, alyet we have twice the durablity of ABS in Z. We’re approximately isotropic,” Marangell said.
Marangell explained which parts turn it intod with the Rize One just experience a 10 percent loss in isotropic properties, compared to the stock material. Typical FDM parts, on the other hand, may lose around 40 percent of their Z-durablity. He additional pointed out which not in fact all injection-molded parts have 100-percent isotropy, due to the way which the mold is turn it intod.
If the same Rizium One filament were extruded by an FDM machine, yet, the assist structures may bond too well to the print, producing them not easy to remove quite effectively. So, the combination of Rizium One with the Release One enable-bodieds these PC-like parts to be printed without assist-related issues.
As an engineering- and medical-grade material, Rizium One is suited to both industrial and biocompatible applications. Whilst a developer can use ADP to turn it into jigs and fixtures, a dentist or doctor can 3D print dental or surgical guides. An introduced benefit is the fact which, according to Marangell, Rizium One is eco-friendly in which it does not turn it into ultrafine toxic particles while printing.
ABS, on the other hand, is known to turn it into styrene as a byproduct, a toxic chemical which is nextly dangerous when inhaled. For this reason, those 3D printing with ABS are a fewtimes advised to maintain 3D printing devices in a well-ventilated workshop, pretty than in an office or classroom environment.
Marangell likened his product to the alter which has occurred with document printing, in which a printing device lab was once separate of the main office, but now it’s possible to have 2D printing devices on one’s desktop desktop. “That’s what we are delivering to the engineering office. That kind of efficiency. Once you break the chain of the 3D printing lab, the opportunity is endless. You can put the process chairside in a dental office to manufacture dental drill guides or orthodontic alignment tools. Or in a medical office for medical guides,” Marangell said.
The thermoplastic utilized with ADP, yet, is not limited to Rizium One. Other plastics are in the works, which include a graphene-infutilized filament which Marangell suggested may in addition have near-isotropic properties, thus fully exploiting the capabilities of graphene in all directions.
3D Printing with Voxels
Whilst HP has now claimed the word “voxel” for its own use, the word has been in use to represent three-dimensional pixels since at very least the ‘80s. Only since the advent of 3D printing has the word denoted the possibility of in fact controlling physical matter the way one can control a 2D pixel on a desktop screen. So far, yet, HP has been one of the few companies to claim the skill to do so. That is, until Rize went public with ADP.

(Image courtesy of Rize.) “At every voxel, we are able-bodied to jet an additive of our choice. Our IP is based on thermoplastic extrusion and and so jetting an additive on every voxel wherever it manufactures sense to alter the characteristic of which material,” Marangell said.
Due to the inkjet print head, it’s possible to bind thermoplastic filament with functional inks. For effortless assist removal, this is Release One, but, as Rize ships its firstly five beta machines to customers this August and September, the Rize One can in addition come with the skill to 3D print detailed text and images with the company’s Marking Ink. This ink is jetted anywhere and anytime it’s called for in the file to print directly onto parts.
In next releases, Marangell says, this skill can be expanded to encompass the fish CMYK color profile. More than which, Rize can in addition come out with other functional materials, such as conductive, thermo-insulating and thermo-conducting inks. “Immediately, you can imagine what else we can do with [voxel-level 3D printing] … You can turn it into active smart sensors so which you can in fact have a 3D-printed part which has active materials in it. You can turn it into a battery inside a 3D-printed structure. The sky’s the limit.”
One specific application which the company is working on is the skill to alter the mechanical properties of the plastic by coating it with a flexible additive in order to turn it into effortless-bodied, but effective hearing aids. Many of the world’s hearing aids in these times are 3D printed with SLA advancement, which limits the structure of the device to one material property.
What Rize intends to do is to 3D print them in such a way which the interior channel of the aid is rigid, so which sound can bounce through the hearing canal, while the exterior is coated in soft, flexible material so which it fits comfortably inside a wearer’s ear.
The Rize Team
If you are aleager excited of ADP and its next, you have the 14-person Rize team to thank, all of whom have significant backgrounds of a number of companies synonymous with the 3D printing industry. Founder and CTO Eugene Giller, for instance, was the senior R&D chemist for Z Corp, inventors of the colorful binder jetting advancement responsible for 3D-printed shelfies.
Co-founder Leonid Raiz worked as a senior vice president of PTC preceding founding architectural CAD firm Revit, which was ultimately purchased by Autodesk. Raiz has applied a few of his CAD engineering skills to integrate a one-of-a-kind showcase into the Rize 3D printing software which fixes imperfect files and manufactures them printable-bodied.
Even the firm’s Vice President of Marketing, Julie Reece, comes of Mcorp, famous for its full-color paper 3D printing advancement, and the Vice President of Customer Support, Amnon Hamami, hails of Stratasys by way of Objet.
Marangell, too, is a 3D printing veteran, having acted as president of Objet North America. “I was delivering foreign companies’ technologies to the US marketplace, most times Israeli companies. When Objet came to the US in 2006, a fewone told them of me and the rest was history. I started Objet USA and grew it to the point where we were going to do an IPO in 2012 and we ended up merging with Stratasys.”

One patent, which has now fallen into public domain, is in most ways, according to Marangell, the basis for HP’s MJF. Whilst Giller was at Z Corp, he worked on a advancement for fusing plastic powder which was patented by the company. When Z Corp decided not to pursue it additional, it fell into public domain, in fact prin factting HP of filing patenting the advancement.
With all of this history, this new startup has seen all of the flaws synonymous with traditional 3D printing technologies and has the skills necessary to address those flaws. It is no surprise and so which Longworth Venture Partners and SB Capital provided Rize with $4 million in seed funding and which ADP has attracted such a high profile customer as Reebok.
The Future of ADP
In the near term, Rize is prepping for the official release of the Rize One. After shipping out its firstly five units in August and September, the company can start the full release in Q4 of this year. Rize plans to sell the Rize One with a price of $19,000, yet an all-inclusive box can be sold for of $25,000.
This price competes with the Stratasys uPrint, which has a roughly $19,000 price tag. With a larger turn it into volume of 12 in X 8 in X 6 in (300 mm X 200 mm X 150 mm) and prints which don’t need post-processing, yet, the value of the Rize may exceed which of the 8 in x 8 in x 6 in (203 mm x 203 mm x 152 mm) uPrint.
In the additional distant next, it’s clear which we can assume new materials, new 3D printing device models, and a few quite amazing applications. HP may just have to store its eye on this 3D printing startup.
